A glossopharyngeal nerve palsy is paralysis of the ninth cranial nerve.
Clinical features include:
- loss of sensation - tested by the gag reflex
- loss of taste sensation on the posterior 1/3 of the tongue
The competence of cranial nerves IX and X are usually tested with an overlapping set of tests, thus:
- palatal movement - the gag reflex
- quality of speech:
- the ability to cough
